DETAILED DESCRIPTION OF THE INVENTION

[0019] Referring to the drawings and initially to FIGS. 1-3, a packagesupport device for a compact disc in accordance with the preferredembodiment of the present invention comprises a support disk 10.

[0020] The support disk 10 has a center formed with a through hole 11.The support disk 10 has a first side formed with a plurality of(preferably four) V-shaped protruding ribs 12 each extended from acenter to a periphery of the support disk 10. The protruding ribs 12 ofthe support disk 10 are spaced from each other and arranged in aradiating manner. The first side of the support disk 10 is formed withan annular inner rib 14 intersecting each of the protruding ribs 12 andan annular outer rib 13 intersecting each of the protruding ribs 12. Theannular inner rib 14 and the annular outer rib 13 of the support disk 10are concentric with each other. The annular outer rib 13 of the supportdisk 10 is located at the periphery of the support disk 10. Each of theprotruding ribs 12 of the support disk 10 is provided with an arcuateraised locking rib 15 which is located at an inner edge of the annularinner rib 14. The support disk 10 has a second side formed with amounting recess 16. The mounting recess 16 of the support disk 10 has anannular wall formed with an oblique chamfered portion 161.

[0021] The package support device in accordance with the preferredembodiment of the present invention further comprises a cylindricaladvertising paper 30, a central post 40, and a cylindrical contractionfilm 50. The central post 40 has an end formed with a resting plate 42.The resting plate 42 of the central post 40 is formed with an insertionsection 41. The insertion section 41 of the central post 40 has acruciform shape.

[0022] The procedure for packaging a plurality of compact discs 20 isdescribed as follows.

[0023] First of all, a first support disk 10 is mounted on a supportrack 60 as shown in FIG. 4, with the mounting recess 16 of the firstsupport disk 10 being directed upward. Then, a plurality of compactdiscs 20 and the cylindrical advertising paper 30 are mounted on thefirst support disk 10 as shown in FIG. 4A, with the advertising paper 30being coated around the compact discs 20, and with the lower end of theadvertising paper 30 being mounted in the inner periphery of themounting recess 16 of the first support disk 10. Then, the compact discs20, the advertising paper 30 and the first support disk 10 are removedfrom the support rack 60 as shown in FIG. 4B. Then, a second supportdisk 10′ is mounted on the resting plate 42 of the central post 40 asshown in FIG. 4C, with the mounting recess 16 of the second support disk10′ being directed downward, and with the insertion section 41 of thecentral post 40 being inserted into the through hole 11 of the secondsupport disk 10′. Then, the central post 40 is inserted into the centralhole 21 of each of the compact discs 20 and the through hole 11 of thefirst support disk 10, so that the second support disk 10′ is mounted onthe compact discs 20 and the advertising paper 30 as shown in FIG. 4D,with the upper end of the advertising paper 30 being mounted in theinner periphery of the mounting recess 16 of the first support disk 10.Then, the cylindrical contraction film 50 is heat sealed between theannular inner rib 14 and the annular outer rib 13 of the support disk10, thereby accomplishing the packaging process of the compact discs 20as shown in FIG. 4E.

[0024] As shown in FIGS. 5 and 6, two package support devices arelaminated in a vertical manner, wherein the arcuate raised locking ribs15 of the lower support disk 10 of the upper package support device andthe arcuate raised locking ribs 15 of the upper support disk 10′ of thelower package support device are arranged in a staggered manner, therebyforming an interlocking action, so that the two package support devicesare laminated rigidly and stably.

[0025] As shown in FIG. 7, when the user wishes to remove thecontraction film 50, the user can press the recesses formed between theprotruding ribs 12, the annular inner rib 14 and the annular outer rib13 of the support disk 10 so as to break and tear the contraction film50. After the contraction film 50 is removed, the advertising paper 30and the upper support disk 10′ of the upper package support device areremoved, thereby exposing the compact discs 20 for use. The uppersupport disk 10′ of the upper package support device can be mounted onthe compact discs 20 when not in use.

[0026] Accordingly, the package support device for a compact disc inaccordance with the preferred embodiment of the present invention hasthe following advantages.

[0027] The package support devices are laminated rigidly and stably bydesign of the arcuate raised locking ribs 15 of the support disk 10 ofeach of the package support devices, so that the compact discs 20 can belaminated and supported rigidly and stably.

[0028] In addition, the mounting recess 16 of the first support disk 10provides a rigid support effect to the advertising paper 30, therebyfacilitating packaging of the compact discs 20.

[0029] Further, the recesses are formed between the protruding ribs 12,the annular inner rib 14 and the annular outer rib 13 of the supportdisk 10, thereby facilitating the user breaking and tearing thecontraction film 50.

[0030] Further, the central post 40 is combined with the support disk 10to support the compact discs 20 rigidly and stably, thereby providing apositioning effect efficiently.

[0031] Although the invention has been explained in relation to itspreferred embodiment(s) as mentioned above, it is to be understood thatmany other possible modifications and variations can be made withoutdeparting from the scope of the present invention.
